DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultra-high tower tower, and more particularly to an ultra-high tower tower whose main tower structure is formed by using an RC outer peripheral column.

[0002]

2. Description of the Related Art Conventional tower towers include, for example, the following (1) to (3). (1) As shown in FIGS. 8 and 9, the tower 1 has a thin and high truncated cone-shaped main tower 1A formed on a ground G by a steel frame (hereinafter referred to as S frame). At the upper end of the main tower body 1A, a short cylindrical observation deck 2A is constructed by connecting it to the upper end of the main tower body 1A.

Is constructed and connected to the upper side of the observation deck 2B to form a conical spire 3B by RC construction.
Are equipped with multiple antennas.

(3) FIG. 12 and FIG.

An observatory 2C is constructed, and a conical spire 3C is constructed at the upper end of the observatory 2C by RC construction, and a plurality of antennas are installed on the spire 3C. As shown in FIG. 14, a compressive force Pg due to the weight of the tower-like tower 1 always acts on the foundation of the tower-like tower 1. When a horizontal force Fh due to wind or earthquake acts on the tower 1,

[0004]

With the rapid movement toward digitization of broadcasting and communication, plans for digital antenna towers (radio towers) have emerged in various places. It is preferable that the antenna tower be as high as possible from the viewpoint of functions such as widening the terrestrial reception area and attractiveness of the observatory for sightseeing in limited location conditions. There is a demand for an ultra-high tower tower of 5 or more. In the 300m class tower, like Tokyo Tower and Eiffel Tower,
There are S-structures with good wind permeability, but all have a tower ratio of about 4. Overseas structures having a height of 300 m or more and a tower ratio of 5 or more are often made of RC structures having weight and excellent stability, instead of lightweight S structures, in order to prevent overturning against wind. The tower tower in Japan has a 200m class RC chimney.
Structures with a height of 300 m or more and a tower ratio of 5 or more have not yet been built. In order to meet the needs of ultra-high towers in Japan, the development of new structural systems that further develop the existing ultra-high structural technology has been urgently needed to respond to severe load conditions compared to overseas for typhoons and earthquakes. I have.

[0005] When a tower of 300 m or more is made of a steel frame, the wind permeability is good. However, in order to reduce the pulling force Fms and maintain stability due to its light weight, it is necessary to make the building wide at the foot. However, there is a disadvantage that a large site area is required. In addition, when an observation deck or the like is provided at the upper part, the period becomes long because the rigidity of the steel frame is small, and eddy excitation in a strong wind and shaking in a long-period earthquake become a serious problem. Further, the S-structure has a disadvantage that it is inferior to a concrete material in terms of cost and construction period. On the other hand, an RC structure having a length of 300 m or more is the first attempt in Japan, and the existing proposed technology is only an extension of the RC chimney technology up to the 200 m class. Overseas examples are those with less damage from typhoons and earthquakes, and are basically cylindrical or similar to a chimney, or have a petal-shaped closed section with three or more projections.
The diameter is changed, and ribs are provided on the lower part to resist overturning. However, this type of structure is not rational for Japan's ultra-tall towers because of the concerns of the effects of eddy excitation during strong winds and the increase in wind pressure and loads during earthquakes. There is.

The tower-like tower 1 of the above (1) has good permeability for wind load because of S structure, and vortex excitation for
Although no vortex is generated in the main tower, the rigidity of the main tower is small and its oscillation period is long. Regarding the seismic load, even if it is lightweight, it has a great effect on a slightly long-period earthquake. As for the sway, the stiffness is small, so the sway is easy. As for the burden on the foundation, the pulling force is large, so the burden is large. In addition, the construction period is not only long and the workability is poor, but also the unit price of steel frames is high and the economic efficiency is not good. The tower-like tower 1 of the above (2) has a small resistance due to the wind because the wind load is a cylindrical structure made of RC. Regarding vortex excitation, the effect of the vortex on the observation deck is small because the vortex is generated in the main tower, the rigidity of the tower is large, and the cycle of the vibration is short. As for the seismic load, since the weight is large, the influence of the earthquake is great. As for the shaking, since the rigidity is large, the shaking is difficult. Regarding the load on the foundation, the tower is heavy, so the compressive force on the foundation increases. In addition, it is easy to construct, the construction period is short, and the workability is good, but it requires a large amount of concrete and is not economical. The tower-shaped tower 1 of (3) is of a cross tube type made of RC with respect to the wind load, so that the resistance due to the wind is large. Regarding the vortex excitation, there is no vortex generated in the main tower body, the rigidity of the tower body is large, and the cycle of the vibration is short. As for the seismic load, since the weight is large, the influence of the earthquake is great. As for the shaking, since the rigidity is large, the shaking is difficult. As for the burden on the foundation, the weight of the tower increases, so the compressive force on the foundation increases.
In addition, it is easy to construct, the construction period is short, and the workability is good,
It requires a large amount of concrete and is not economical.

An object of the present invention is to provide an ultra-high tower-like tower which does not have the above-mentioned disadvantages of the prior art. It is an object of the present invention to provide an ultra-high (for example, a height of 300 m or more) tower tower having a tower ratio of 5 or more, which consumes relatively little and is economically excellent.

[0008]

The tower according to the present invention has an observatory structure on a main tower structure, a spire on the observatory structure, and a spire. In an ultra-high tower with a tower ratio of 5 or more, in which the antenna is installed on the body, the outer part of the main tower structure is a vertical direction between a number of RC outer peripheral columns and the outer peripheral columns. It is composed of a truncated cone-shaped or truncated pyramid-shaped outer shell of a ramen frame composed of a number of RC circumferential beams connected at a number of positions spaced apart from each other, and the inner part of the main tower structure is It is characterized by a frame structure in which a central pillar standing at the center and each outer peripheral pillar are connected by radial beams at a number of positions vertically spaced from each other. It is assumed that. When the circumferential beam is made of S or SRC, workability is improved as compared with the case of using RC.

In a preferred embodiment of the present invention, the following (A) to (E) are performed. (A) The outer part of the main tower structure is composed of a number of RC outer peripheral columns arranged at equal angular intervals and a number of circumferential beams arranged at intervals in the vertical direction. And is composed of a truncated cone-shaped outer shell of a ramen frame that is connected so that a number of quadrilateral frames are formed, and the inner part of the main tower structure is located at the center of the main tower structure. A ramen frame is formed by connecting the upright central pillars and the outer peripheral pillars at a number of positions vertically spaced by radial beams. (B) The circumferential beam connecting the outer peripheral column and the outer column and the radial beam connecting the central column and the outer column are arranged at substantially the same level. (C) The outer peripheral side column body of the main tower structure is constituted by an RC hollow body made of high-strength rebar and high-strength concrete. (D) The observation deck structure and the spire are S-shaped. (E) The center pillar is formed of an S-shaped hollow body, and an elevating facility such as an elevator can be installed in the hollow part. In addition, if necessary, a square set formed by the outer peripheral column and the circumferential beam of the main tower structure and / or the central column, the outer peripheral column 21, and the radial beam are used. A brace is provided within the quadrilateral frame to stiffen the quadrilateral.
